java - 全息圆形进度条速度

Question

我很难理解 HoloCircularProgressBar ( https://github.com/passsy/android-HoloCircularProgressBar ) 动画的工作原理。当我尝试将 animate(mHoloCircularProgressBar, null, 1f, 1000) 更改为 animate(mHoloCircularProgressBar, null, 1f, 10000) 时，持续时间不会乘以十。相反，动画会变得断断续续，并且仅在值小于 1000 时才平滑。如何减慢 HoloCircularProgress 栏的速度，使其以给定的毫秒值前进？

下面的例子应该对你有帮助。

private void batteryLevel() {

    BroadcastReceiver batteryLevelReceiver = new BroadcastReceiver() {
        public void onReceive(Context context, Intent intent) {
            context.unregisterReceiver(this);
            int rawlevel = intent.getIntExtra(BatteryManager.EXTRA_LEVEL, -1);
            int scale = intent.getIntExtra(BatteryManager.EXTRA_SCALE, -1);
            float level = -1;
            if (rawlevel >= 0 && scale > 0) {
                level = (rawlevel * 100) / scale;
            }
            //batterLevel.setText("Battery Level Remaining: " + level + "%");
            animate(pgbTablet, null,level, 10000);
            animate(pgbCase, null, level, 10000);
            tvTblCharging.setText(""+(int)Math.ceil(level));
            tvCaseCharging.setText(""+(int)Math.ceil(level));
        }
    };
    IntentFilter batteryLevelFilter = new IntentFilter(Intent.ACTION_BATTERY_CHANGED);
    getContext().registerReceiver(batteryLevelReceiver, batteryLevelFilter);
}
